Abstract
Cell lines have been produced that secrete human monclonal antibodies capable of binding to the lipopolysaccharide molecules of selected Pseudomonas aeruginosa IATS serotypes. Pharmaceutical compositions containing these antibodies, which can be in combination with other monoclonal antibodies, blood plasma fractions and antimicrobial agents, and the prophylactic and therapeutic use of such compositions in the management of infections are included.
Claims10
A method for inhibiting the viability of Pseudomonas aeruginosa organisms, comprising:
- exposing said P. aeruginosa, in the presence of complement and neutrophils, to a viability inhibiting amount of a human monoclonal antibody or binding fragment thereof which specifically binds to an accessible determinant of outer membrane of P. aeruginosa lipopolysaccharide IATS serotype 2 and 5 and Fisher immunotype 3, wherein said monoclonal antibody inhibits the viability of organisms of at least two of said IATS serotypes and immunotype in the presence of the complement and neutrophils.
A method for inhibiting the viability of Pseudomonas aeruginosa organisms, comprising:
- exposing said P. aeruginosa, in the presence of complement and neutrophils, to a viability inhibiting amount of a human monoclonal antibody or binding fragment thereof obtained from ATCC CRL 9171 which specifically binds to an accessible determinant of outer membrane lipopolysaccharide of P. aeruginosa IATS serotype 4 and 11 and Fisher immunotype 2.
A method for inhibiting the viability of Pseudomonas aeruginosa organisms, comprising:
- exposing said P. aeruginosa, in the presence of complement and neutrophils, to a viability inhibiting amount of a human monoclonal antibody or binding fragment thereof obtained from ATCC CRL 9258 which specifically binds to an accessible determinant of outer membrane lipopolysaccharide of P. aeruginosa IATS serotype 6 and 13 and Fisher immunotype 1.
